Mon XXe siècle

Born in Budapest, Lila (Dortha Segda) and Dora (also Segda) are twin sisters who, after being orphaned in childhood, are adopted by two different families and separated. Purely by chance, they both book passage on the Orient Express on the same day, but while Dora is the mistress of a rich man, Lila has become a terrorist with intentions of blowing up the train. Meanwhile, elegant passenger Z (Oleg Yankovsky), romances Dora and is spurned by Lila -- but he has no idea he's dealing with twins.
